l SPECIFICATION forming part of Letters Patent No. 749,806, datedJanuary 19, 1904.

Application filed February 24, 1903. Serial No. 144,756. (No model.)

T all whom, t may concern:

Be it known that I, EDWARD RUE, a citizen of the United States,1residingat Amboy, in the county of Blue Earth and State of Minnesota, haveinvented a new and useful Windmill, of which the following is aspecification.

The invention relates to improvements in windmills.

The object of the present invention is to improve the construction ofwindmills and to provide a simple and comparatively inexpensive one ofgreat strength and durability adapted to run at a uniform speed in highwinds and capable of being readily operated to arrange its blades out ofthe wind for stopping it.

A further object of the invention is to provide a windmill of thischaracter having ahorizontal wind-wheel provided withyieldablymountedblades'adapted to feather and capable of swingingautomatically to present less fan-surface to the wind when the latterincreases in force beyond a predetermined point.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of the upper portion ofa windmill constructed in accordance with this invention. Fig. 2 is aperspective View of the entire apparatus. Fig. 3 is a vertical sectionalview, the parts being arranged as shown in Fig. 1. Fig. 4 is ahorizontal sectional view.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l designates a tower, designed to be constructed in any suitable mannerand provided at its top with a suitable bearing and receiving arotaryframeor turn-table 2, antifriction-balls 3 or other suitableantifriction devices being preferably located between the rotary frameand the turn-table or cap-piece of the tower. The cap-piece is providedwith a central bearing opening through which passes a vertical shaft 4,which is suitably connected with the rotary frame or turn-table. Therotary frame or turn-table is provided at shafts.

its upper and lower portions with bearings for the reception of upperand lower shafts. The upper bearings and 6 are arranged in pairs atopposite sides of the top of the rotary frame toreceive the upper shafts7 and 8, which are arranged in different horizontal planes to en- Hablethem to clear each other, and the bearings, which consist, preferably,of approxif mately L-shaped arms, form lower shoulders 9 and 10,arranged to be engaged by cams 11 `disposed above the bearings 14 topermit the flower shafts 15 and 16 to clear each other.

These shafts are provided with cams 17 and 18, which are arranged toengage the shoulders of the bearings 13 and 14 to limit the rotation ofthe lower shaft.

The upper and lower blades 19 and 20 are provided with sleeves 21,located above the center and extending longitudinally of the blades andprovided at their inner ends withcams 22, which engage projections 23 ofthe These sleeves form housings or casings for coiled springs 24,disposed on the shafts and connected with the same and with the sleevesand holding the cams yieldably in engagement with the projections 23,which are preferablyv in the form of antifriction devices. Theseantifriction devices consist of antifriction rollers or sleeves mountedon pins which extend through and project from opposite sides of theshafts.

The blades of each shaft are arranged at right angles to each other, andwhen one blade is in a vertical position the other will be in ahorizontal position. The blades are pivotally or hingedly mounted on theshafts above the center, and the cams limit the rotary movement oftheshafts. .The blades at one side of the windmill will present their facesto the wind to be operated on by the same, and those at the other sidewill be arranged edgewise of the same as they come into the same,thereby 'or otherwise injuring theJ parts.

reducing the resistance to a minimum. Should the wind increase in forcebeyond a predetermined point the power of the coiled springs, they willbe turned to a greater or less degree out of the wind and will presentless fan-surface to the same. As soon as the force of the wind abatesthe cams and the springs will return the blades to their normalposition.

Extending from the inner ends of the sleeves, which are fixed to theblades, are arms 25 and 26, located adjacent to the cams and provided attheir outer ends with antifriction devices 27 and 28, which are arrangedto be engaged by upper and lower rings 29 and 30. rIhe depending rods orbars 3l are rigid on the ring 29 and project through the open ends ofthe guide-arms 29, which are carried by the turntable 2, and the lowerextremities of the rods terminate `in feet which normally rest upon thering 30, so that an upward movement of the ring30 will impart a likemovement to the ring 29, at the same time permitting the ring 29 torotate independent ofthe ring 30, which is held against rotation by therods or bars 34, which connect it to the slide 32, arranged on thevertical shaft 33 at a point below the top of the tower. The Aslide isprovided with a suitable eye 35, which is connected with one end of arope or cable 36 or other flexible connection extending upward from theslide to a guide-pulley 37. The flexible connection 35 is preferablyattached to one end of a coiled spring 38, which has its other endattached to a wire 39 or other -suitable operating means which extendsto the base of the tower for enabling the vertically-movable rings to beraised to engage the arms and turn the blades to a horizontal position,as illustrated in Fig. 2 of the drawings. When the blades are arrangedin a horizontal plane, they present their edges to the wind, and thewindmill is thereby stopped. The coiled spring of the operating deviceforms an elastic or yieldable connection and enables the operating ropeor cable to be pulled to a position for holding the blades in ahorizontal plane, and the latter will be gradually turned tosuch-position without liability of straining As soon as the operatingrope or cable is released the springs of the blades will return the sameto their normal position.

The central vertical shaft 4 has its lower end stepped in a suitablebearing, and it is provided at its lower portion with a rotary cam 40,which extends between a pair of antifriction devices 41 of avertically-reciprocating rod 42, and the latter is connected with apump-rod 43, whereby a reciprocatory motionwill be imparted to the samewhen the windmill is in'operation. rIhe slide, which is approximatelyU-shaped, is provided at its ends with sleeves 44, arranged to slideupon` the vertical shaft 4 and located above and below the cam. Theslide is also provided with a lug or projection 45, which is guided on aframe 46, as clearly shown in Figs. 2 and 4. Any other suitable meansmay be employed for communicating motion from the central vertical shaftto the device or machine to be operated, and the blades may be made ofany desired size to secure the necessary power, and, if desired, onlyone set of shafts and blades may be employed.

It will be seen that the windmill is simple and comparativelyinexpensive in construction, that it is strong and durable, and that itis adapted to run at a uniform speed in high winds. It will also be seenthat should the force of the wind increase and overcome the springs theblades will be turned more or less and expose less fan-surface, therebyeffectually preventing the windmill from being injured by rotating toorapidly in heavy storms and high winds.
